IMPROVEMENT IN MACHINES FOR NAILING SHOE-SOLES WITH WIRE..

The Schedule referred to in these Letters Patent and making pazco the same.

To all persons to whom these presents may come;

Be it known that l, Louis Gonne, a citizen of' the Dominion of Canada, having resided the year preceding-in the United States of America, and made oath of intention to heroine a citizen thereof, and being now a resident of Boston, ot' the county ol' Suf'- folk, and State of B'lassachusetts, have made a new and useful invention, having reference to the Nailng of Slice-Soles, or various other Articles, with Wire; and I do hereby declare the same to be l'ully described in the following specilication, and represented in the accompanying drawings, aplmrtenant thereto.

Of such drawings- Figure l is a frontelevation oi' a machine embodying my invention.

Figure 2 is a side view of it.

Figure 3 is a longitudinal section of it, taken through the transfer-rer.

Figure 4 is another such section, taken through the movable cutter.

Figure. 5 is a transverse and vertical section, taken through the feed-wheel.

ln this machine, the feeding ofthe wire into the transferrer, as well as the severing of the nail from the wire, and transferringot` the nail to the'nail-driver, and driving suoli nail into a sole or other body, are effected by mechanism, combined with and actuated by the shank ofthe nail-driver, during the upward and downward movements thereof.

The stock ofthe machine is shown at A, it being formed so as to be readily grasped in one hand of an operative.

It has a nose-piece, I, and au adjustable edgegauge, K, as hereinal'ter mentioned.

1t also has a transtiu'rer, O, and a movable knifeearrier or lever, H.

There is also, within the frame, a curved passage, fr, for the reception ofthe strip oi' wire, s, and the conveyance of it l'rom the feed-wheels into the transferrer,

The shank of the nail-driver a. is shown at B, such shank being provided with ahead, l).

C' and l) are the feed-wheels, or wheels for feeding the strip ot' wire along through the strip-passage a', as fastas may be necessary, there being, to the larger of these feed-wheels, a ratchet, d, which, fixed to the said leed-wheel, is supported on a stationary pivot or journal, e.,

The lesser' feed-wheel is simply a presser-wheel, its journals being supported by a spring, f, which presses the wheel closely against the strip ot' wire, so as to crowd it up to the milled periphery of the largcrteedwheel.

A rocker-lever, l", formed in manner as represented inthe drawings, and arrz'inged' alongside oi' the said ratchet, and having the journal-pin e as n. fulcrvunn carries, at its upper part, a pawl, f, to operate with the dentatcd periphery of the ratchet.

During' each descent of the shank ot' the nail-driver, a -cannned and slotted projection, or arm, G, extended from such shank, and formed in n'ianner as exhibited, will be driven against the lever l", and will turn it on its fidel-mn, in a manner to force the paw] against the ratchet, and canse it to be revolved more orless, so as to feed the wire ibrward.

A, spring, ll', suitably applied to the stock-and the level', serves to eli'ect the retreat or return movement of the lever, and to move such lever until a projection, g, of it is brought up againsta stop, It, extended from the nail-gauge l'.

This nail-gauge l is an elastic arm, pivoted, at one end, to the stock A, the pivot being shown at i.

When turned ou its fulcrum, such arm passes over a curved rack or notched projection, 7:, extended from the stock in manner as represented.

The arm should be made with a project-ion or rib on its under surface, suoli rib being to enter either` oi' the notches l of the rack k, and engage thearm therewith, so as to arrest the stop hl in position.

By means of the notched projection or rib L, the catch-lever or nail-gauge I and the stop h, the extent ot back movement of the pawl of the lever F may be determined, for the purpose of effect-ing, by the forward movement of the lever, the proper advance or feeding of the wire.

As the nail-wire is moved forward, it passes into the transierrer O, whose lower part, q, is tubular, to receive the wire.

rThis transfert-er is a lever, arranged within and pivoted to the stock, its fulcruxn being shown at 1'.-

lhe lever is moved in one direction by the naildriver shank while descending, the reverse movement oi' the translhrrer being effected by a spring, s, iixed to the stock, and arranged, relatively to the transferrer, in manner as exhibited in the drawings.

The lower end of the shank of the nal-driver is semispherieal, as shown at t, for the purpose of actuating the translerrer, whose upper arm is cam-shaped, as shown at n, to cause the transfert-er to be actuated by the shank.

lrurthermore, there is within the shank a stationary knife, n', to operate with a movable cutter or .knil`e, c, carried by a lever, H.

This lever is arranged within and pivoted to the shank, its fulcrum being shown at wv.

lhe upper arm ol' this lever is bevelled, as shown at sv', to cause the lever to be moved in one direction, viz, such as to advance its knife up to the stationary knife by the nail-driver carrier during its descent.

A spring, y, project-ed from the stock and against tue lever, serves t0 eiect a reverse movement of the cutter lever, at the proper time or times.

To thenail-driver and the stock, a spring, z', is applied, its purpose being to raise the shank or carrier of the driver after each descent of it.

'At the lower part of the stock, and projected thereiiom, and formed in manner as represented in the drawings, is what may be termed the nose-piece I. rlhis, at its lower end, is to rest direc-tlyon the sole to be nailed; an adjustable gauge, K, fastened to the stock, and arranged with the nose-piece, in manner as shown in the drawings, serving, by resting,r against the edge of the sole, to determine the proper distance therefrom at which each of the nails is to be driven.

In the operation of this machine, the wire, after having passed into the transferrer, is next eut by the knife. N ext, the piece severed, will be transferred to and directly underneath the driver, which, next de'- scending upon the piece of wire, will force it into the sole. The workman next tilts and moves the machine forward the proper distance for anothernail to be driven, after which, he, by a downward blow on the head of the driver-carrier, causes another advance of the wire, and another piece of it. to be removed from the strip and driven into the sole.

I .claim the combination of the eannned project-ion or arm G, or its equivalent, with the shank B of the naii-driver a, and with other mechanism, substantially as described, or its equivalent, for feeding the strip of nail-wire along, the whole being:r so constructed, that during each downward movement of the said shank, the percussive force or blow employed for effecting such movement, shall put in operation the feedingmechanism, so as to cause t-he wire to he fed forward, ds explained.

LOUIS GODDU.
